Plot Synopsis

When a program named Dyson arrived for a tour of General Tesler's fleet, Tron, inwardly boiling with rage, plotted with Beck to capture him. Beck protested that if Dyson was brought back to Tron's hideout, he would have to be derezzed in order to keep Tron's secret safe, but Tron insisted that it was the only way.

As Beck worked on making the capture, worrying about his increasingly erratic mentor, Paige and Pavel showed a supercilious Dyson around Argon City. Pavel eagerly brought Dyson's attention to the trouble caused by the mysterious renegade, hoping to discredit and displace Tesler.

Meanwhile, Tron, brooding over Dyson's presence, thought back to the days before the war, when Dyson had been his right-hand security program. Along with three others, they had faced trouble in the ISO District when an unseen individual threw an identity disc from a crowd of ISOs and derezzed a Basic, sparking a riot; Dyson had sustained a disfiguring facial injury in the mess, which inflamed his hatred of ISOs. When even the arrival of Kevin Flynn brought no relief to the strained conditions on the Grid, Clu had staged his long-planned coup, with Dyson, a traitor, at his side.

Beck's first attempt to capture Dyson failed when the veteran security program sensed the trap he had set. Returning to Tron, Beck attempted a strategem to convince him that he could steal Dyson's disc instead of capturing him, eliminating the need to derezz him. Tron, enraged, disclosed that Dyson's death was the whole point of the exercise. Beck, trying to stop him, was stunned and knocked out with a light taser, and Tron retrieved the half-disc they had shared and went after Dyson himself.

Spoilers end here.
